Me and two of my friends bought three early last year. Theirs are stiff and rough. Mine was incredibly rough and stiff. Upon inspection, we saw a hump on the action in the right side bolt rail area, a burr like protrusion on the top right rear part of the action, and the rail channels on both sides looked like a jack hammer was used to mill them out. After several hours with files and a stone it is now slick as can be. If I had not got such a good deal i would have sent it back. I was surprised something like that made it out. When you can see humps, ridges, and chatter with the naked eye it's bad. But, it shoots extremely well! Some stone work on the other two made them slick. Mine was just horrible though.
